This invention relates to a method of formin channels and the like from strip material.

An object of the invention is to provide a method of making deep channels in thin material without buckling or warping the same.

Another object of the invention is to provide a method of the described class whereby, deep channels may be formed in thin material, and at the same time provide a reversed or ogee curve in the cross section of the same.

Particularly, the invention contemplates the use of a power roll machine for forming ogee gutter, such as attached to the eaves of houses.

These andother objects of the invention will become apparent from the following description of the accompanying drawing, wherein:

Figure l is an elevational view of a pair of rollers comprising the first stage of the operation of the present invention. v Figure 2 is a view similar to Figure 1, but showingthe second stage of operation.

' Figure 3 is a view similar to Figure 2 and showing the third stage of operation.

Figure 4 is a view similar to Figure 3 and showing the fourth stage of operation.

Figure 5 is a view similar to Figure 4 and showing the first step in forming the ogee curve and the rearwardly projecting attaching flange.

Figure 6 is a view similar to Figure 5 and showing the sixth stage of operation.

Figure 7 is a view similar to Figure 6 and showing further development of the ogee curve and the rearwardly projecting flange.

Figure 8 is a side elevational view of the rollers arranged in their relative positions, and particularly showing the manner in which the strip stock is fed into the machine, as well as the various stages of forming.

Figure 9 is a side elevational view of a machine embodying the present invention and showing the means employed for driving the various rollers.

Figure 10 is an elevational view of a pair of rollers for initially forming the said stifiening flange of the gutter.

Figure 11 is a view similar to Figure 10, but illustrating a step which further forms the referred to stiilening flange, and v Figure 12 is a lateral sectional view taken on lines ll-Jl of Figure 10 and showing a typical arrangement for driving the vertically disposed side rollers.

Accordingly, the exemplary form of the invention shown includes a frame I supporting upper and lower horizontal rollers 2 and 3. The frame '3' Claims. (01. 153-28) 2 .i also supports vertically disposed side rollers das' shown in Figure 12.

As shown in Figure 9, the machine is provided with a prime mover 5, such as an electric motor,

which is connected by a belt 6.-With a driven pulley l, the axis of whichis parallel with the axes of the heretofore referred to upper and lower rollers 2 and 3. The driven pulley 1' is supported on a shaft 8 which, in turn, is supported upon a base 9.

Sprockets ID are secured at each endof the driven shaft 8 and alternately drive upper and lower sprockets l I and I2 afiixed to the horizontal shafts l3 and M which, respectively, support and engage the upper and lower rollers 2 and 3, and are accordingly connected by driving chains 15.

In order to carry out the proper direction of rotation of the upper and lower rollers 2 and 3, idling sprockets I6 may be rotatably supported by the frame I at suitable places.

Referring now to Figure 12, those stages of operation requiring vertical rollers 4 include vertical shafts I! rotatably supported by the frame I and are driven by beveled gears l8 and i9 secured, respectively, to the lower horizontal shafts l4 and the said vertical shafts I 1.

Referring now to Figure 9, the strip material 20 is fed into the machine by a pair of feeder rolls 2 and 3 and are particularly shown in Figure l. The last described arrangement comprises the first stage of operation. The second stage of operation, shown in Figure 2, is similar to the said first stage but diflers in that the upper roller 2 is relatively narrow, whereas, the lower roller 3 includes opposing conical portions to form the material 20 in the shape of a flat-bottomed shallow V-shaped channel in cross section.

The third stage of operation, illustrated in Figure 3, is substantially the same as the second stage, but further forms the material 20 to provide a, deeper channel.

As shown in Figure 9, the axes of the shafts l3 and I4 are disposed so as to feed the material 20 in the form of an arc during the first three stages. The purpose of the last described arrangement is to prevent buckling of the partially formed and angularly extending sides of the material 20, and is a feature of the present invention.

The fourth stage of operation, illustrated in Figure 4, includes driven vertical rollers 4 which form a U-shaped channel of the material 20.

The fifth stage of operation is similar to that of Figure 4, but difiers in that one of the vertical rollers 4 is conical in shape, as at a, to coact with a corresponding .conical portion b at the side of the upper horizontal roller 2 when the thickness ofthe material is passed therebetween. The other vertical roller 4 is outwardly curved, as at c, to coact with a projection d on the other side of the upper horizontal roller 2. The flat bottom portion'of the partially formed material 2|] is acted upon by a driven lower horizontal roller 3 in each of the various stages. The periphery of the upper roller projection d is arcuate to conform with theepcrtion c, of the, vertic al roller 4.

The sixth stageiof operation,gshownin Figure-6, issimilar to the fifth stage of operation but includes an additional projection e on the upper.

horizontal roller 2 and an additional step I in one of the vertical rollers 4. -Ati'. theisameitiinethe connecting flange of the materialifl is fur.-

ther formed by changed angles' ofthe' conical,

portions a and b of the rollers 4 and 2.

The seventh stage of operation is substantially the same as the sixth, but includes variations inthe profiles of the various rollers 2 and Wand their projections 41, b, c, d, e; and f.
